Golf Putter Head with Improved Alignment-Aid Design

ABSTRACT

A golf putter head with improved alignment-aid design is disclosed. The golf putter head includes a base having an alignment mark; a body set on the base, having a lateral formed with a face and a top formed with a window corresponding to the alignment mark. Thereby, when the player aligns the window with a ball and a target beyond the ball, and adjusts his/her posture to make his/her line of sight reach the alignment mark through the window, the face is properly positioned with respect to the ball.

BACKGROUND OF THE INVENTION

1. Technical Field

The present invention relates to golf equipment, and more particularly,to a golf putter head with improved alignment-aid design, wherein theputter head has improved alignment-aid design that helps the player tonot only align a ball with a target but also swing the putter and strikethe ball with an appropriate body posture that contributes to successfulputt.

2. Description of Related Art

A conventional golf putter typically has a shaft and a head. The headhas in front a face. In use, a player holds the shaft to swing theputter and in turn impact a golf ball by the face.

For accurately aiming the ball, the conventional golf putter usually hasthe head provided with an alignment line, which may be in the form of agroove, a raised rib or a painted line. When preparing to hit a ball, aplayer, under assistance of the alignment line, is able to make the faceperpendicular to the center of the ball and the target direction, so asto well aim the ball at the target.

While being effective in aiming the ball at the target when being suchplaced that an invisible horizontal line is formed by linking thealignment line, the ball center and the target, the existing alignmentline of the conventional golf putter fails to make the player's posturecontributive to successful putt. In other words, even when the playerstands with an improper posture or with his head bias, he/she can stillalign the alignment line with the ball and the target. Consequently, theplayer stands improperly may be nevertheless convinced of the apparentalignment and make a wrong strike. As it is a common failing of manygolf players during aiming to unconsciously have habitual faulty posturedue to individual dominant eyes and head tilt for aiming, it would bedesired to have a putter head that has improved alignment-aid design tohelp the players to not only align a ball with a target but also swingthe putter and strike the ball with an appropriate body posture thatcontributes to successful putt, thereby breaking the functionallimitation of the existing alignment lines.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a golfputter head with improved alignment-aid design, wherein the improvedalignment-aid design helps to correct players' habitual faulty posturedue to individual dominant eyes and head tilt for aiming.

To achieve this and other objectives of the present invention, a golfputter head with improved alignment-aid design according to the presentinvention is attached to a golf putter shaft and comprises: a baseconnected to the golf putter shaft and having an alignment mark thereon;and a body set on the base and having a lateral formed with a face and atop formed with a window corresponding to the alignment mark so that aplayer holding the golf putter shaft is allowed to have his/her line ofsight reach the alignment mark through the window. In use, the playeradjusts his/her posture until his/her line of sight reaches thealignment mark, which means the player's line of sight, the window andthe alignment mark are on the same invisible straight line. Thisinvisible straight line and an intended ball route include anapproximately right included angle, so as to ensure that the face isperpendicular to the ground so as to position the face at the optimalposition for hitting the ball.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIG. 1 through FIG. 3, the present invention provides agolf putter head with improved alignment-aid design. The golf putterhead is attached to a golf putter shaft 100 and comprises a base 10 anda body 20.

The base 10 is connected to the shaft 100 and has an alignment mark 11thereon. The alignment mark 11 may be a painted line.

The body 20 set on the base 10 has a lateral formed with a face 21 and atop formed with a window 22 corresponding to the alignment mark 11. Thewindow 22 may be a slot, and a vertical distance L exists between thewindow 22 and the alignment mark 11. A shelter member 23 is extendedfrom the window 22 along the vertical distance L, so as to ensure thatthe line of sight of the player 200, the window 22 and the alignmentmark 11 are aligned straightly and accurately. When the player 200 seesthe alignment mark 11 through the window 22, the line of sight of theplayer 200 links the window 22 and the alignment mark 11 as an invisiblestraight line. This invisible straight line and an intended ball routeinclude an included angle θ1, which is a right angle or an approximatelyright angle.

Thereby, player 200 may adjust posture to make his/her line of sight,the window 22 and the alignment mark 11 come into a straight line so asto lead to successful putt. At this time, the face 21 is perpendicularto the ground and perpendicular to the center of the ball 110 and thetarget. This is the optimal position of the face 21.

Basing on the aforementioned structure, the operation of the presentinvention and the principles on which the operation bases are explainedin detail below.

Referring to FIG. 4 in addition to the previous three drawings, assumingthat the line of sight of the player 200 and the intended ball route aredefined as X and Y axes, respectively. In particular, when the player200 adjusts his/her posture to make his/her line of sight reach thealignment mark 11 through the window 22, the invisible straight linelinking his/her eye, the window 22 and the alignment mark 11 is theforegoing line of sight of the player 200, namely the X axis. At thistime, the window 22, a ball 110 to be hit and a target to which the ballis hit are in another invisible straight line, namely the intended ballroute or the Y axis. As shown in FIG. 3, the included angle θ1 includedby the X and Y axes is approximately a right angle. When the player 200is not posturizing properly, the player 200 can only see the window 22,and cannot see the alignment mark 11 through the window 22.

Referring to FIG. 5, in a second embodiment of the present invention,the alignment mark 11 may be a reflector or a light-emitting object.Thus, before the player 200 swings the putter, the player 200 has toadjust his/her posture until his/her eyes looking at the window 22 see alight reflected or emitted from the reflector or the light-emittingobject, which means that the face 21 is perpendicular to the ground andthe X and Y axes include an approximately right included angle θ1. Inthis case, the shelter member 23 serves to block excessively reflectedor emitted light from interfering with the sight of the player 200 tocause misjudgement of the player 200. Thereby, the present inventionfacilitates correcting habitual faulty posture of players due toindividual dominant eyes and head tilt for aiming, so as to improveaccuracy of aiming.

Referring to FIG. 6 and FIG. 7, in a third embodiment of the presentinvention, a golf putter head with improved alignment-aid design sharesthe same principles with the previous embodiments while featuring thatthe alignment mark 11 is a cross and the window 22 is a square hole, sothat the player 200, when well posturing, can have his/her line of sightseeing the square hole and the cross alignment mark 11 aligned, so as tomake sure that the face 21 is perpendicular to the center of the ball110 and the target.

The present invention has been described with reference to the preferredembodiments and it is understood that the embodiments are not intendedto limit the scope of the present invention. Moreover, as the contentsdisclosed herein should be readily understood and can be implemented bya person skilled in the art, all equivalent changes or modificationswhich do not depart from the concept of the present invention should beencompassed by the appended claims.
